Hi. I wanted to install plasma 5 on my laptop, but I encountered a lot of problems regarding dependencies, masking and other stuff.
Since I felt a little stubbornness in myself, and didn't want to back off ! I took another approach. I checked that what packages will be installed. After that I removed the qt4 and installed all of the required qt5 packages from qt-5.4.0 one by one and using the specific version. After that I did the same with qt-framework packages and so on. I think that this is generally a bad idea, because the it makes the World set much bigger. However I am wondering what will happen when the tree updates? I mean for examples when another version of qt5 comes out, portage will try to update it ? thanks.
